How to Frame Art Prints Without Hiding the Edges
Measure the paper and image before choosing a frame. A mat or spacer keeps the print off the glass, while a careful fit keeps borders and lettering in view.
Start with the print you actually have. Measure the sheet, then the image and any white borders. Use the worked example below to see how the sheet, mat window and frame fit together.
Measure the Sheet and the Image Separately
A print sold as 18 × 24 inches may have an image that reaches the edge, or a smaller image surrounded by white paper. Those are different framing jobs. Do not order a mat from the product title alone.
A frame's stated size commonly describes the size of artwork or glazing it holds. Its visible front opening is usually smaller because the frame lip overlaps the edges. Its outside dimensions are larger. Ask the seller which measurement is being quoted.
A 12 × 18 Print in an 18 × 24 Frame
Here is a portrait example for a full-bleed print with no essential detail at the edge. All dimensions below are width × height in inches. The mat overlaps the paper by ⅛ inch on each side. A framer should adjust that overlap if a signature or border needs to stay visible.
| Part | Example size (inches) | What the measurement means |
|---|---|---|
| Paper sheet | 12 × 18 | The actual sheet, measured edge to edge. |
| Mat window | 11¾ × 17¾ | The opening is slightly smaller than the sheet. |
| Mat outside / frame fit | 18 × 24 | Confirm that this is the size the frame holds. |
| Visible mat border | 3⅛ on each side | Outside mat dimension minus window dimension, divided by two. |
| Finished frame outside | Depends on the molding | Use the seller’s outside dimensions for your wall outline. |
Choose a Mat or Use Spacers
A mat adds space around the picture and helps keep it away from the glazing. For a print you want to preserve, choose a conservation-quality mat and backing suited to the work. A full-bleed picture can also be framed without a mat, with spacers to keep it off the glass or acrylic.
The Library of Congress framing advice explains suitable boards and mounting methods. Avoid household tape, spray adhesive and permanent glue on art you want to keep. For a valuable or fragile sheet, have a trained framer choose the mounting method.
Keep the Important Edges in View
Check the dancers' hands in La Danse, the ornamental border of an Art Nouveau poster and the text on A Room of One's Own. A neat frame is a poor fit if it hides the part you wanted to see.
A float mount shows the paper edges against a backing. A canvas floater frame surrounds a stretched canvas with a gap. They are different display methods, so show the framer the actual print rather than asking only for a “float frame.”
Choose the Glazing and Frame
Glass and acrylic protect the front from handling and dust. Acrylic weighs less and is harder to break, but scratches more easily. Its static can be a problem for loose or flaking material. Anti-reflective glazing can reduce distracting reflections.
UV-filtering glazing reduces UV exposure. It does not stop damage from all light. The National Archives' display guidance explains why keeping a work out of strong light still matters.
Try a simple frame beside the picture before deciding on an ornate one. A light mat can separate Klimt's dense patterns from a busy room. A dark frame can give a strong boundary to Matisse's bright colors. The choice should help you see the art.
Assemble and Hang With Care
- Clean the glazing and let it dry before assembly.
- Set the glazing, mat or spacers, mounted print and backing into the frame.
- Check for dust and make sure nothing presses or bends the sheet.
- Secure the backing and use hanging hardware rated for the finished weight and wall type.
- Test the height with a paper outline from your usual viewing position.
Keep the finished print away from direct sun, damp spots and heat sources. If you are still choosing dimensions, return to the poster size guide. If the work is stretched canvas, compare its different edge and framing needs in canvas versus paper.
